Hi Kerim,

you currently have 20°C at Iskenderum. That means that cold start should not be a big issue even of your thermotime switch or cold start valve do no work.

Can you measure fuel pressure when car stands a few days and will not start? And can you please just start ignition without engine and just push down gas pedal. Do you hear injector ticker then?

hallo dr volker
ok. I will do it.and , I will write result.
thanks

guten abend dr.volker( for turkei )
After 3 days, I want to repeat what I need to do and be sure.
1) First of all, I will connect the manometer to the fuel pipe next to the cold injector.
2)I'll just turn on the ignition (I won't start the starter) should I just measure the pressure this way without touching the accelerator pedal?
Or should I measure the pressure by pressing the accelerator pedal? Or should I just turn on the ignition and measure the pressure, then press the pedal to measure the pressure a second time?
which?
thanks

Merhaba Kerim,

when you switch on ignition your fuel pump will start to run for 1-2 seconds. At least after doing that twice you should see 2 Bar without fast dropping now. Do not touch gas pedal or start engine yet. Switch ignition off and watch for 20 minutes how pressure drops.

Now switch ignition on again and press down gas pedal and listen to enigne. You should hear that injectors ticker while moving gas pedal down.

Never leave ignition on for too long without starting engine. That might kill ignition coil, power resistors, ignition module. If you need to do so, remove pin 15 from ignition coil.

hi dr.volker,
thanks ,
I will do to morrow. Last Thursday, it worked hard with an additional battery. I will share this stage with you with a photo.
best regards

good morning dr. volker,
 As you said, I measured the fuel pressure of the car that has not been running for 3 days. it is 2 bar.
I am sharing pictures with you. The first picture is 2 bars.
I waited 20 minutes in the ignition off position.
The pressure remained at 1.9 bar. (second picture)
Then I turned on the ignition. I pressed the gas pedal all the way down. I heard "Clicks" sounds on the throttle stick. I'm not sure if these sound injectors?I tried to start the car. I cranked it 2 times, but it didn't work. The battery got weak. Then, after I gave additional charge to the battery from my other vehicle, the vehicle started at the first cranking. When I turn the vehicle off and start it again after 10 minutes of running, the vehicle starts quickly at half-start. The problem is only if the vehicle waits for 2 days or more without working, it does not work during the first start...
thanks
